For the gift, start research and development of graphene batteries

Chapter 71 Market Turbulence
In fact, the formation of carbon-based batteries did not take long.

In about a month, the samples of lithium batteries have been made.

The speed can be so fast, this is the credit of Mr. Wang Mingyang.

Until recently, old man Wang Mingyang has done nothing, focusing on the research and development progress of carbon-based batteries.

You know, the lack of cathode materials has become more and more serious recently.

Due to the limitation of raw materials, the price of traditional lithium batteries on the market has risen absurdly.For an ordinary power bank, the price is about three times that of the previous one.

Thinking about more than 300 yuan and buying a 10000mAh power bank, I feel uncomfortable no matter how I think about it.

The current situation is that even if the market demand is reduced because of the price problem, it cannot meet the demand of the remaining people for commodities.

In this case, the price of the product can only go up without limit until the rest of the people can't afford it.

This is the same as the reduction in grain production. Many people say that the 10% reduction in grain production this year will have no impact on ordinary people. The big deal is that the price will increase by 20%.

The price of food is so low, a 20% increase will not have a big impact.

For people with such thoughts, Jiang Ming could only chuckle.

The market always needs food, and it is irreplaceable.

With a 10% gap, if it cannot be replenished, only 10% of the people will have no food to eat.

These 10% of people will not watch themselves starve to death, they can only desperately buy food, and use all their wealth to buy food.

There is no way not to snap up, life is the most important thing.

Under this kind of thinking, the other 90% of people will also join the tide of panic buying, otherwise they will become the part of the 10% who are short of food.

Under the tug-of-war between the two sides, the price of food will soar, not double or triple, but tens or hundreds of times.

When it reaches 10% of the population, they can no longer afford food and starve to death.

The market is so cruel. In the face of survival, the ruler of money will become chaotic.

Although other commodities do not have the attributes of a necessity such as food, the reason is the same when a commodity is in short supply to a certain extent, or some people and some industries urgently need it.

Its confusing price cannot be deduced with common sense.

In fact, at the current level, only some necessary or small projects can continue to advance.Projects such as other energy storage power stations and large buses cannot be advanced.

The devastation to the industry has already appeared.

Seeing this situation, Wang Mingyang was also extremely anxious.

If carbon-based batteries can be released one day earlier, the anxiety of the entire industry can be alleviated earlier.It plays a vital role in the stability of the entire industry.

Therefore, Wang Mingyang took a project team and ran around non-stop. Up to now, the problem of carbon-based batteries has been basically solved.

Kyoto, Lithium Battery Research Institute, although it is already night, the test building is brightly lit.The heads of the main units responsible for the research and development of carbon-based batteries gathered to witness the roll-out of carbon-based batteries.

Although it was just a sample off-line, everyone was very excited.

This is a brand new battery model, which represents another battery design idea.

It took more than five months from the beginning of research and development to the final sample of the carbon-based battery, which has to be called amazing speed.

During these five months, hundreds of industry units and thousands of supporting manufacturers have contributed their strength to the research and development of carbon-based batteries.

Jiang Ming remembered that there was a manufacturer who made fiber tape for the packaging protection of the battery.

The fiber tape itself is relatively common, but the glue used in it, according to the standard of carbon-based batteries, traditional materials cannot meet the requirements.

In this case, the founder of the company, along with technical staff, researched and prepared all the glues that could be found on the market, but ultimately failed to find a glue that met the requirements.

In this case, ordinary companies may give up and say they can't do it.

But this manufacturer didn't give up. Since it couldn't find it on the market, it developed it by itself.

For this reason, this manufacturer found a research institute that makes materials for aerospace under the Xia Ke Academy, and specially developed this product.

In order to develop this product, the amount of money consumed is uncountable.

In this case, this section of fiber tape, the problem of glue, can be regarded as a formal solution.

There is also a company that provides grinding equipment.

Because in the production process of lithium batteries, a lot of grinding equipment is required, and the hardness is required to be very high.

In the lithium battery industry, generally, if you want to buy equipment, they are all customized, and the shortest delivery time is half a year.

In order to catch up with the progress, the equipment manufacturer dismantled the equipment for its own use, and used the main components for the equipment for the production of carbon-based battery materials.

Their own equipment was dismantled and production was affected. The equipment manufacturer did not complain.

For this, Jiang Ming felt sorry for them.

Although there is a relationship with the New Energy Industry Association, at this moment, thousands of manufacturers are concentrating and working hard to shorten the research and development cycle to five months.

You should know that the general battery cell research and development cycle is calculated in years, not to mention carbon-based batteries, this brand new battery.

It is not easy to make samples in such a short period of time.

Carbon-based batteries have come out, and traditional lithium batteries, but from the appearance, there is a big difference.

Traditional lithium batteries are generally made of aluminum shells, and the surface of the entire battery is that bright silver color.This is determined by the color of the aluminum shell material itself.

As for the carbon-based battery, because the carbon powder is used to wrap the shell, the shell of the carbon-based battery is the kind of matte black.

It feels a little rough to the touch.

Use graphene carbon powder to wrap the case, which is required.

Because graphene batteries have the characteristics of smaller size and higher density than traditional batteries.This characteristic means high energy density and large discharge current.

But correspondingly, the calorific value per unit volume will be much higher than that of ordinary batteries.

According to thermal simulation calculations, the heat generation of graphene batteries will be about 50% higher than that of traditional batteries.

Of course, this is running at full power, and ordinary equipment really can't use such a high power.

If you really use such a high discharge power, you must have a water-cooling system, otherwise you won't be able to hold it down.

This kind of full power is generally aimed at the instantaneous discharge of vehicle power batteries, which are not used like ordinary consumer batteries.

Energy density test.

The simplest indicator to measure the energy stored in a battery is that it can hold more power per unit mass.

Jiang Ming remembered that the energy density of the previous graphene sample was 580Wh/kg.This value shocked everyone at the time.

After all, the energy density is directly doubled above the traditional technical level.
